This Weekend's Special

This weekend we have the Kart XACT Fit kit, in a 6 Inch 10mm with a Clark/Para Ramp.  We have slashed the prices from $285.00 down to $200.00.  That's an unheard of savings of $85.00 on a Kart XACT Fit Kit.  We only have a handful of these Kits at this price.  These 10mm XACT Fit Kits are perfect for building that custom 6" 1911 hunting hand gun or that long range 1911.

New Lower Prices 

We have lowered our pricing on our Multi Groove Magnetic Vise Jaws.  These are currently selling for $17.50 to $19.50 on other WEB sites.  Our current pricing is $8.98 for the 4 inch vise Jaws and $9.98 for the 6 Inch Vise Jaws. 


1911 Short Block - 45ACP - Classic 

Our 1911 “Short Blocks” are perfect for do-it-yourself shooter or custom Gunsmiths looking for a head start with our quality components. Our Short Block kits come with a slide, frame, and barrel fit together using the same components and methods we use for our full builds at a fraction of the cost designed to save you time and money on your next project.  We will be adding different Calibers and configurations over the next few months.
